Some more advice on temporary buildings today;
There is no prescriptive size limit which applied to ‘temporary buildings’ however the guidance below should give and indication what may be permissible:
In order for field shelters to be exempt from requiring permission this generally depends on a number of factors:
1. Size & construction – in the event the temporary building is required to be constructed on site, this would constitute operational development and planning permission would be required. If
the shelter is ‘ready made’ when arriving on site this would not constitute ‘operational development’.
2. Physical attachment to the land – the temporary building should not be fixed to the ground and should purely rest on the ground. In the event the temporary building is fixed to the ground in anyway and/or is connected to drainage pipes, has a water or electricity supply etc, planning permission would be required.
3. Permanence - the temporary building should be easily movable (by tractor or other machinery) so to ensure this does not constitute a permanent structure. The temporary building should be moved on a regular basis, again to ensure the structure does not have a degree of permanence.
These definitions have been established in a catalogue of planning case law such as R (Save Woolley Valley Action Group Ltd) v Bath and North East Somerset Council [2012] and Skerritts of Nottingham Limited v SSETR [2000].
The chicken sheds in the Woolley case are huge - 1000 hens and approximately 120m2, so 20 metres by 6 metres by 3.5 metres high!! Compared to my paltry 10m2 shed
